B58 Series Regulator Residential Regulator

B58 Series Regulator Residential Regulator The B58 regulator is ideally suited for use where inches of water column or pounds delivery pressure are desired for uses including utility services, small boilers, and other similar applications. The B58 is ideal for situations where rapid response is required, such as on/off loads, and can be utilized to avoid shock problems. Description B58R The B58R is a spring-loaded, self operated regulator with an internal relief (designated by the letter R ) valve. The 1" or optional ¾" internal relief valve provides excellent relief capacity. B58N The B58N is the same as the B58R (above) with the exception that it does not have an internal relief (designated by the letter N ) valve. This model may be used in situations where an over-pressure internal relief valve is not required. Option Designations R Internal Relief N No Internal Relief HP All models for outlet pressures above 0.5 PSIG Benefits Light weight Easy to install Smooth control over widely varying inlet pressures No special tools required for outlet pressure adjustment Features Field interchangeable orifice Field interchangeable adjustment spring 27 sq. in. diaphragm area Spring-loaded internal relief valve assembly Wide range of NPT valve body sizes Primary and secondary informational badges (4 lines available with 24 characters per line) Serial numbers available upon request SPECIFICATIONS

CORRECTION FACTORS FOR NON-NATURAL GAS APPLICATIONS The B58 may be used to control gases other than natural gas. To determine the capacity for gases other than natural gas, multiply the values within the capacity tables by a correction factor. The table below lists the correction factors for some of the more common gases: Gas Type Specific Gravity Correction Factor (CF) Air 1.00 0.77 Butane 2.01 0.55 Carbon Dioxide (Dry) 1.52 0.63 Carbon Monoxide (Dry) 0.97 0.79 Natural Gas 0.60 1.00 Nitrogen 0.97 0.79 Propane 1.53 0.63 Propane-Air-Mix 1.20 0.71 To calculate the correction factor for gases not listed in the table above, use the gases specific gravity and insert it in the formula listed below: Correction Factor (CF) = Where: SG 1 = Specific gravity of the gas in which the capacity is published. SG 2 = Specific gravity of the gas to be controlled. Wide Open Flow Calculations For wide-open orifice flow calculations use the following equations: For P 1/P 2 < 1.89 use: Q K P2( P1 P2) For P 1/P 2 > 1.89 use: KP1 Q 2 Where: P 1 = Absolute Inlet Pressure (PSIA) Q = Flow Rate (SCFH) P 2 = Absolute Outlet Pressure (PSIA) K = Orifice Coefficient (SCFH/PSI) 6

VENT LINES FOR REGULATORS When constructing vent lines to be attached to regulators installed indoors, follow a few basic rules: a. Never use pipe sizes smaller than the vent size; smaller pipe sizes restrict the gas flow. If a long gas run must be used, advises increasing the pipe one nominal size every ten feet to keep the flow restriction as low as possible. b. Keep the vent line length as short as possible to minimize the restriction and reduce the vent's tendency to cause regulator pulsation. c. Support the vent pipe to eliminate strain on the regulator diaphragm case. d. Always point outdoor vent pipes in the downward position to reduce the possibility of rain, snow, sleet, and other moisture entering the pipe. Install a bug screen in the end of the pipe. e. Do not locate the vent line terminus near windows, fans, or other ventilation equipment. See the installation instructions furnished with the regulator. f. Adhere to all applicable codes and regulations. g. If your vent pipe causes regulator pulsation, consult your sales representative or manufacturer. h. strongly recommends running a separate vent line for each regulator. Headers with various installed devices can cause regulator malfunction. Caution Ensure the end of the vent line is away from ANY potential ignition sources. It is the installer s responsibility to ensure the vent line is exhausting to a safe environment. INSTALLATION Warning does not endorse or warrant the completeness or accuracy of any third party regulator installation procedures or practices, unless otherwise provided in writing by. Follow your company's standard operating procedures regarding the use of personal protection equipment (PPE). Adhere to guidelines issued by your company in addition to those given in this document when installing regulators. a. Remove all shipping plugs from the regulator inlet, outlet, and vent before installation. b. Verify the piping interior and regulator inlet and outlet are clean and free of dirt, pipe dope, and other debris. Dirt and other foreign materials entering the regulator can cause a loss of pressure control. c. Apply pipe joint sealant to the male pipe threads. Do not use pipe joint material on the regulator's female threads. Joint sealant could become lodged in the regulator and cause a loss of pressure control. d. Gas must flow through the regulator's valve body in the direction cast on the regulator body. Gas flowing in the wrong direction can overpressure and cause damage to the regulator. e. For the B42, B31, B58, B34, and B34S models, the diaphragm casing can be mounted in any position relative to the body through a full 360 angle at 90 increments. B57, B34, and B38 models can be mounted in a full 360 angle. f. When the regulator is installed OUTDOORS, the vent must always be positioned so that rain, snow, moisture or foreign particles cannot enter the vent opening. It is recommended that the vent be positioned to face downward so as to avoid entry of water or other matter which could interfere with the proper operation of the regulator. The vent should be located away from building eves, window openings, building air intakes and above the expected snow level at the site. The vent opening should be inspected periodically to insure it does not become blocked by foreign material as outlined in DOT PHMSA-RSPA-2004-19856. g. When the regulator is installed INDOORS, the vent must be piped to the outside atmosphere while using the shortest length of pipe, the least number of elbows, and having as large a pipe diameter as the vent size or larger. USING VENT PIPE ANY SIZE SMALLER THAN THE VENT CONNECTION WILL LIMIT THE REGULATOR S INTERNAL RELIEF VALVE CAPACITY. The outlet end of the pipe must be protected from moisture and the entrance of foreign particles. The regulator should be specified by the user with the size vent and pipe threads desired to make the vent pipe connection. 37

START-UP PROCEDURE a. Mount a pressure gauge downstream of the regulator to monitor the downstream pressure. b. With the downstream pressure valve closed, slowly open the inlet valve. The outlet pressure should rise to slightly more than the set-point. c. Verify there are no leaks and all connections are tight. d. The regulator was pre-set at the factory to match order specifications. If necessary, adjust the outlet pressure by removing the seal cap on the top of the spring housing and rotating the ferrule or adjustment screw inside the spring housing. Adjusting the outlet pressure requires either a ratchet with a socket and an extension or a large flat-head screwdriver. With a small amount of gas flowing through the regulator: e. Rotate the adjustment screw clockwise to raise the outlet pressure. f. Rotate the adjustment screw counter-clockwise to lower the outlet pressure. g. Replace the seal cap and check for leaks after the desired outlet pressure is achieved. The regulator is ready for operation. SAFETY WARNING This product, as of the date of manufacture, is designed and tested to conform to all governmental and industry safety standards as they may apply to the manufacturer. The purchaser/user of this product must comply with all fire control, building codes, and other safety regulations governing the application, installation, operation, and general use of this regulator to avoid leaking gas hazards resulting from improper installation, startup or use of this product. strongly recommends installation by a qualified professional and periodic inspection of pressure regulators (inspections may be required by local applicable codes or regulations). Inspections should include checking for gas quality, cycle numbers, external environmental changes, and operating conditions that impact wear on the regulator's moving parts. To ensure safe and efficient operation of this product, replace worn or damaged parts found during inspection. 38
